GREAT CROPS OF STRAWBERRIES AND HOW TO GROW THEM

SCENES ILLUSTRATING THE RAPID AND VIGOROUS DEVELOPMENT OF KELLOGG THOROUGHBREDS 
TWO views of the country estate of Mrs. Edith Lockwood. Put-in-Bay, Ohio. Scene No. 1 shows KelloKK plants three weeks 
after setting. Scene No. 2 is the same plot photographed six weeks later. Mrs. Lockwood writes us under date of May 18, 
1<)13- "I am immensely proud of my Kellogg strawberries, and they certainly are a picture just now. It may interest you to 
know that the State has taken six acres of our country home for the Perry Memorial. They have cut down all our line trees 
and a monument is going up within a few hundred feet of us. We shall have that on one side of us and the Kellogg straw- 
beries on the other. Of the two 1 prefer the^ellogg monument to the mile-high Perry one.' ' Certamly. the plants are beauties. 
than the maintenance in the soil of ample quan- 
tities of plant food — in one word, a well-balanced 
ration. 
Barnyard Manure and Green Manure 
AS a general rule barnyard manure, especially 
that from the horse stable, will keep up the 
plant-food supply in a soil that is fairly balaneed 
at the outset, but it is quite important that crop 
rotation be practiced, and we advise our patrons 
to grow some leguminous crop such as winter 
vetch (also known as sandy vetch, or hairy 
vetch), or soy beans, cow peas or clover, and 
plow this under. This is an ideal form of green 
manure. The leguminous crop not only will 
supply large quantities of humus to the soil, but 
nitrogen as well, and such a rotation will insure 
the purifying and renewing of the soil, and will 
put it into ideal condition for another setting of 
strawberry plants. After plowing under this 
leguminous crop, scatter evenly over its surface 
400 pounds of acid phosphate to the acre. The 
"dish" then will be well filled. 
Some Other Valuable Fertihzers 
IN giving precedence to the fertilizer supplied 
by the horse stable we would not exclude other 
forms of animal fertilizer from the strawberry 
field. The cow stable, the hog pen, and the 
chicken coop— all may be drawn upon for supplies 
of fertility, and each and all will add greatly to 
the upbuilding of the soil. Caution must be ob- 
served, however, in employing chicken droppings, 
for they are very strong and very heating. We 
not only advise their moderate use, but especially 
urge that they be diluted before applying to the 
soil where strawberries are to be grown. Mix 
them in the ratio of two parts of dry earth or 
dust to one part chicken droppings, scatter them 
thinly over the ground and plow them under 
deeply, just as would be done in the case of barn- 
yard fertilizer.. 
Concerning Commercial Fertilizers 
AS to so-called commercial fertilizers, it is ap- 
parent that the methods we advocate above 
are by far the most economical for securing plant 
food. But wherever the grower finds it impos- 
sible to grow green manure, such as legumes as 
above suggested, or to secure barnyard or other 
forms of animal fertilizer, then we advise com- 
mercial fertilizers, and these should be purchased 
direct from reliable houses in an unmixed state, 
the mixing to be done by the purchaser. As 
phosphorous and potassium disintegrate slowly, 
they should be applied, if possible, ten days to 
two weeks before plants are set and thoroughly 
mixed with the soil. But, as nitrogen becomes
